Hi
Some time ago, I had a problem, when, after changing anything in Display settings and clicking "OK" my game crashed and all settings reverted to the original ones.
That way I could not change the resolution, filtering etc... and was stuck with a tiny game window and bad graphics
I contacted Game support, and despite their efforts, they could not help me to fix that issue
But, today, accidentally, I've found the problem:
Apparently, if you have a G-Sync or a Free-Sync in your Nvidia panel set to both fullscreen and windowed - the game crashes.
But, if you only set it to Fullscreen - the game works fine!
I can, finally, enjoy Distant guns once more!!!
